Franklin le dragon adore les histoires et en lire aux autres, mais tout le monde a trop peur de le regarder. Un jour, il rencontre une fille nommée Luna qui, loin d'être effrayée, est fascinée par Franklin, ayant récemment lu un livre sur les dragons. Ils deviennent immédiatement amis et parlent sans cesse de leurs lectures : des livres sur le roller, le roi Arthur, les araignées et le kung-fu. Ensemble, ils élaborent un plan pour partager leur passion des livres en ouvrant une librairie volante, directement sur le dos de Franklin !

Franklin the dragon loves stories and loves reading stories to people too, but everyone is too scared to even look at him. One day he meets a girl named Luna who, far from being scared, is fascinated to meet Franklin, having recently read all about dragons in one of her books. They instantly become friends and talk non-stop about what they've read: books about roller skating, King Arthur, spiders and how to do kung fu. Together, they hatch a plan to share their love of books with others by opening a bookshop - a flying bookshop, that is - right on Franklin's back!
